I made a modern version of the Rotula for the 2026-2060 period. A feeling of magic at work when you find that the predicted dates match the ones found on the web, to the nearest day...
My version is made with #TeXLaTeX (TikZ) with some #Python .
I started making paper astronomical models during Covid: I didn't know such nice paper models existed...
As usual, everything you need is available on my website for download. Print & cut out the wheels and follow the instructions on the 12-page PDF. I wrote a user guide in french, and also one in english.
